This invention consists .in =improvements in centrifugal disintegrators suitable "for pulainggrain, ore :or other material.

In order that the invention may'beunore easily understood reference .willlbeimade to the accompanying drawings which illustratey an example of disintegrator having my improvements applied thereto.

The disintegrator chamber consists of a circumferential ring j provided with a lateral outlet 5 for the disintegrated material, an upper disk or cover b With central hole c for inlet of the material to be disintegrated. The cover is concave on the inner or under side, in which latter are suitably iXed a number of concentric rows of downwardly pointing round studs or pins CZ. In the chamber is arranged i a rotatable disk g xan@ upper disk: orI cover 4with central lhole ifor receiving the :material 1 to be -z disml.which isl of aconvexitycorrespondingrto the concavityiofthezunderside of the aforesaid chaniberitoponcoverrb.

Mounted 'n fthe fhole v c, li-s itlre lower 1 end -of ha fchute or ffunnel v-e `which provided `withia-sieveforfgrating llheconvex disk "g which'.1s!providedwithfthe con-centricrows of upstanding studs fh is ffm-ed' on I the upper Lend o'fHawertic-alshaftii Yllhe latter revolves in a bearing c of anti-friction metal supported in a sleeve 9 and in a footstep bearing Z of phosphor bronze lixedly arranged in a bush l2 bolted to the base of the casing a. The rows of studs l and z, are of such a diameter and are set so far apart in a. radial direction that they clear each other by about 4 millimeters more or less according to the ineness' of pulverization desired and the diameter of the fixed concave plate and the convex disk is proportional to the output of the apparatus. The shaft is driven in the usual manner by a pulley m which is fixed to the shaft z' by a cone sleeve 13 in two parts,

'which sleeve is placed around the shaft 'i and is connected to the pulley m by bolts lll, screwing into the pulley. By turning the bolts 14, the pulley being held to the shaft by the set screw l5, the coned sleeve is forced into the pulley and tightly wedges the latter to the shaft e". In order to effectually lubricate the shaft` e', which suitably receives 2500 revolutions a minute7 inoi'e or less, a lubricatorwz Fig. 3, is provided which by a pipe 0 conveys the oil to the chamber y) above the bearing 7c and surrounding the uppei end of the shaft. rihe chamber j) is formed by expanding the upper part of the sleeve t) as shown. Bis the oil passes down between the bearing and the shaft f, it comes on to a convex oil shield or disk g fixed to the said shaft and is thrown off by centrifugal action into the annular oil chamber r whence it passes away by a pipe s Fig. 3, to a waste oil receptacle t whence it may be drawn o by a cock u. The chamber r preferably consists of a metal cup having a central hole, the bottom of the cup sloping from the central hole downwards to the walls of the cup. The upper edge of the cup is tianged enabling it to be bolted to the lower iiange l0 of the sleeve 9.

Above the chute c is mounted on columns fu a hopper lw provided at: its lower end with a serrated or longitudinally fluted drum a; on the shaft of which is mounted a tive speed coned pulle Y y which is suitably' driven at the desired speed. The hopper w is curved at its lower end to approximately fit the exterior of the tinted drum which more or less closes the hopper and it is also provided with a regulating slide or gate z having a nut l through which passes a screw 2 mounted so hopper. By

spectively the opening or port 16 in the wall of The said material falls down the chute e to the middle of the convex disk as to be immovable longitudi-Q nally in a bearing 3 on the outside of the; turning the screw Qthe gate a is l lifted or lowered to uncover or to cover reoe pulverized may be accurately regulated.;y

g and isg then thrown outwards by the centrifugal aci-Il tion on to the different rows of studs, one-r uni t'ormly inlverizcd. This latter action is n'rcatlv increased and rendered more perfect owing to the sloped or curved shape of the concave tixed cover t) and the convex revolving disk g. Finally the pulverizcd material reaches thc annular passage l partly incloscd by the portions towards the peripheries of the plate t and the disk g and partly by the ring j. From the passage fl the material passes out by the lateral discharge chute 5 which may be bolted on to the ring j as shown, or formed integrally therewith and in order that none of the material shall penetrate to the bea-rings there is a packing ring or washer (i just below and surrounding the boss 7 of the convex disk y.

l claim:

A centrifugal disintegrat'or comprising a convex disk, the inclination of which is cousiderably less than thirty degrees, means tor rotating said disk, an upper stationary disk having a concavity conforming to the convexity of the first mentioned disk so that the faces of said disks are parallel, means for supporting the stationary disk a suitable distance from the convex disk, means for feeding material into the inclined space between the disks, concentrated rows ot up standing' pins on the convex disk7 and concentric rows of depending pins on the concave disk alternating with those on the convex disk, all the pins of the same vlength and the pins of the rows being closer together near the periphery of the disks than the pins of the rows near the center` whereby the fineness of pulverization of the material is increased from the center towards the periphery.

In testimony whereof l have signed my name to this specification in the presence ot' two subscribing witnesses.
